Application nie-a January 5, 192e, serial No. 79,3%, and in. canada November 1o, 1925.

The invention relates to improvements in fruit juice extractors and anobJect of the invention is to provide a fruit juice extractor particularly adaptable for household use and which will effectively and quickly extract juice from lfruit such as oranges,

and the like and willdischar e the same into a receiving underlying vesse. Y

A fui-ther object of the invention 1s to provide niachine of the above type having the reainer thereofdriven at a comparatively high speed by hand power and to arrange the drivin-g mechanism in a simple inexpensive and durable manner and such that all working parts can be readily inspected for repair or other purposes.

A further object 1s to construct the device so that it is sanitary, that is to say, such that all parts coming in contact with the fruit or the juice thereof can be vreadily removed from the machine for cleaning puroses. v

A further object is to construct the machine s o that there is no possibility of the extracted juice getting into the bearings of the machine.

A further object is to construct the bearings of the machine so that the end thrust of the reamer when the machine is in use iS effectively distributed through ball bearings provided.

With the above more important and other minor objects in view which will become more apparent as`the description proceeds,

' the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference bein had to the accompanying drawing, in Whic f Fig. 1 is a side view' of the complete machine.

Fig. 5 is a vertical sectional view at 5-5 Fi re 3. i

ig. 6 is a vertical sectional `view at 6-6 Figure 3.

ig. 7 is a perspective view of the reamer.

In the drawing like characters 'of' reference indicate p corresponding parts in the several figures. y

The body of the machine is in the form of a vertically disposed standard 1 having two vhorizontally disposed jaws 2 and 3 1ocated at the lower end thereof and a further downwardly extendingfinger 4 which providesr a bearing 5 for a jam screw 6,-the jam screw being threaded through the bearing and provided at the upper end with a disc 7 and at the lower end with a winged finger grip 8. The above construction permits the standard to be fastened easily and quickly to the edge of a supporting structure such as a table 9.

r1`he upper part of the standard forms the back wall of the gear casing, the front wall of which is made from a circular plate 10 having a marginal iange 11. The flange buttsthe front face of the standard and is fastened thereto by suitably located screws 12. 'lhe plate 10 and the standard are pro- `rided with opposing aligned journals or bearing bosses 13 and 14 and beneath the teeth of the gear lwheel 17. The contracted outer end of the counter shaft is received within the bearing 14 and beyond the bearing it is screw threaded to receive an elongated ad]usting nut 22, the adjusting nut carrying a jam scre'w 23 which enga es with the latter end of the counter shaft. he forward end of the counter shaft is also contracted in a location slightlyy in advance of the forward end of the bearing 13 and forms a shoulder at 24.

A collar 25 is permanently secured to the counter shaft in a location adjacent the shoulder 24 and the collar is provided with a cup 26 forming a raceway for ball bearings 27. A thrust washer'28 isA mounted on the counter shaft and retains the ball bearings within the yraceway and the said washerieng es the forward end of the boss 13. The col ar has the outer face thereof slightly tapering and non-circular and is herein shown as square in vertical cross section'.

By loosening or tightening up the nut 22,

' I can give" the`ball bearingsemore or less losA play in the raceway and when the said nut has been adjusted as desired it can be retained in such adjusted position by tightenin up the screw 23.

gl'he reainer 29 presents a rounded nose 30 and a flaring skirt 31 and it is provided j interiorly with a sleeve 32 and a web 33 extending between the inner end of the sleeve and the skirt. The innen-end of the sleeve is enlarged and provided with a pocket 34 complementary to and receiving the collar 25 and it is further centrally bored to receive the forward end of the counter shaft. The nose of the reamer is pointed as indicated at 35 and the exterior faces of the nose and the skirt are provided with slightly spirallin ribs 36.

geom-ding to the above. construction it will be seen that the reamer can be readily put in place or removed, that it is given ample bearing area and that sufficient friction will be developed between the tapering faces of the collar and the pocket to hold the reamer in place when not in use and whilst permitting of the ready removal of the same when desired.

A juice collecting receptacle 37 surrounds the reamer and this receptacle has the forward end thereof contracted, the rear end thereof closed and provided with a centrally located sleeve 38 and the bottom or under side thereof fitted with a discharging spout 39. The bearing 13 is provided on the outer face with a plurality of lengthwise extending suitably spaced ribs 40 and these ribs slidably receive and support the sleeve 38 of the juice collector 37. It will be further observed that the forward end of the sleeve 38 overlies the ball raccway and is outwardly flared and that the rear end'of the skirt overlaps the said sleeve. The juice collector 37 is provided with an L-shaped bracket 41 which is detachably fastened to the top side of the flange 11 by a winged jam screw 42. Obviously after one has removed the reamer 3y pulling it forwardly he can then remove e juice extractor by. undoing the jam screw 2. This allows these parts to be cleaned from time to time so that they can be at all times kept sanitary.

'When the device is to be used the fruit such as an orange, lemon or linie is cut in two and one holds the half of the fruit against the realner and then whilst forcing it backwardly turns the handle 19. The reamer rotates at a comparatively high speed and will v'ery quickly and effectively extract the juice from the fruit, it being understood that the fruit is forced back by hand pressure during the operation. The juices liberated are caught by the collector 37 and flow out through the lip or spout 39 into a receiving vessel provided such as a glass 43.

There is no possibility of any'juicc getting into the bearings as it will be observed that any juice which might drip down over the rear end of the skirt at the top will be caught by the sleeve 38 and will then flow downwardly around the sleeve, drop onto the underlying downwardly inclining portion of the skirt and be discharged onto the underlying part of the collector 37.

What I claim as my invention is 1. In a fruit juice extractor, a rotary reamer presenting a flaring skirt and a stationary juice collector surrounding the reamer and having theY one side open and the other side closed and the closed side pro` vided with a and provided turned flange.

2L In a fruit juice extractor, a rotary reamer comprising a semicircular centrally pointed nose, a flaring skirt extending rearwardly from the nose, exterior spiralling ribs extending 'from the point of the nose rearwardly over the skirt and having their front ends positioned tangential to the point of the nose and an interior Ibearing sleeve extending centrally rearwardly `from the sleeve extending into the skirt at the inner end with an out -nose and having the rear end thereof provided with a non-circular flaring pocket.

Signed at Winnipeg this 1st day of December, 1925.
